4 Claims. (Cl. 19-159) This invention relates to fiber handling deviceshaving a pair of adjacent rotatable rolls between which the fiber ispassed and more particularly to improved adjustable means for biasingthe rolls toward each other thereby to determine the extent to which thefiber is compressed during its passage between the rolls.

In sliver coilers it is desirable to coil the maximum weight and lengthof sliver into a given can size in order that the transporting of thesliver from place to place by moving the sliver can from one operationto another may be accomplished efficiently. The weight of sliverdeposited in a coiler can is controlled in part by the pressure whichthe coiler head rolls exert on the sliver tending to compress thesliver. If, however, the sliver compressing force exerted by the rollsis too great, the sliver may become uneven due to interference with thefree drafting of the fibers. It is therefore obviously desirable tocompress the fiber to an extent suflicient to cause the maximum weightand length to be deposited in the coiler can without interfering withthe free drafting of the fibers.

A principal object of this invention is to cause the maximum quantity ofsliver to be deposited in agiven coiler can size without causing anyunevenness in the sliver.

Another object of this invention is to provide a coiler wherein improvedadjustable biasing means is utilized to provide a desired slivercompressing force.

The invention in one form comprises pivotally mounted support means forone of the rolls of a coiler head, a plurality of indentations formed inthe support means at different distances from the pivotal mountingthereof, and biasing means engageable with the support means at any ofthe indentations to urge the support means and its associated rolltoward a fixed roll thereby to compress the "sliver, between the rollsto a degree determined by the particular indentation or indentationsselected for engagement by the biasing means.

For a better understanding of the invention, reference may be had to thefollowing detailed description taken in conjunction with theaccompanying drawings in which Fig. 1 is a side view of a coiler; Figure2 is a cross-sectional view of the coiler head taken along the line 22of Fig. 1; Figure 3 is a plan view partially in section taken along theline 33 of Fig. 1; Fig. 4 is a side view partly in section of the coilerhead taken along the line 44 of Fig. 3 and Fig. 5 is a side view of abiasing clip comprising an essential feature of the invention. Forconvenience, the section lines 2-2 and 3-3 are indicated on the enlargedFig. 4 as well as on Fig. 1.

With reference to Fig. 1 the numeral 1 indicates a base on which apedestal 2 is mounted by means of bolts 3. Rotatably supported by thebase 1 is a platform element 4 which supports sliver can 5. Disposedwithin pedestal 2 is a driving mechanism which imparts rotary motion toplatform 4 thereby to rotate can 5 about its vertical axis in knownmanner. Secured atop the pedestal 2 is the coiler head generallydesignated by the numeral 6. As is well understood in the art, amechanism disposed within Patented Mar. 10, 1959 pedestal 2 impartssuitable motion to the elements of head 6 so as to coil a sliver intocan 5 in a pretermined pattern. As can best be seen from Figs. 1 and 4,the coiler head 6 comprises a coiler base element 7 secured to the upperend of pedestal 2 in any suitable known manner. Coiler base 7 isprovided at its left-hand side with an upstanding integrally formedportion 7a to which is bolted the sliver guide '8 by means of bolt 9.Coiler base 7 is provided with a cylindrical opening in which a tubegear 10 is rota-tably mounted. Tube gear 10 is provided with a rimportion 11 which rides in a circular groove 12 formed in coiler base 7.Tube gear 10 is also provided with a toothed portion 13 which mesheswith the gear 14 afiixed to shaft 15 and which is therefore rotatedthereby. At its upper end shaft 15 is rotatable within a journal bearingmeans formed in the coiler base 7. Integrally formed with the tube gear10 is the hollow tube 16 which transmits the sliver into the open can 5in known manner.

Mounted to the upstanding portion 7a of the coiler head base 7 is theintermediate element 17 which is pivotally mounted about the pin 18 andwhich at its righthand extremity is provided with a handle 19. Element17 at its left-hand extremity is provided with a flared opening 20 shownin Fig. 3 through which the shaft 15 extends. Pinion 21 is afiixed tothe upper end of shaft 15. A cylindrical opening is formed within theintermediate element 17 for receiving the upper end of the tube 16.Since this particular relationship between intermediate element 17 andthe tube 16 is conventional, the opening formed within the element 17 isnot indicated in the drawing. Affixed atop the-intermediate element 17is a fixed support means 22 secured in position by means of the bolt 23.Support means 22 is provided with a cylindrical sleeve portion 22a inwhich the shaft 24 is rotatably mounted. A bevelled pinion 25 is affixedto the left-hand extremity of the shaft 24 and meshes with bevelledpinion 21 when the intermediate element 17 is in its normal operatingposition depicted in the drawings. It will be understood that when thehandle 19 is moved upwardly to cause the element 17 to rotate in acounter-clockwise direction about pivot 18 as viewed in Figs. 1 and 4,the pinion 25 moves out of engagement with the pinion 21.

Affixed to the right-hand extremity of the shaft 24 as viewed in Figs. 3and 4 is a coiler roll 26 which is one of a pair of cooperating rollsfor imparting movement to the sliver. Also secured to the intermediateelement 17 is the movable support means 27v which is pivotally mountedat the pivot means 28 secured by the bolt 29 to the element 17. Movablesupport means 27 is provided with a cylindrical sleeve portion 27a inwhich the shaft 30 is rotatably mounted. A driven gear 30a is secured tothe shaft 30 and rotary motion is imparted thereto by means of thedriving gear 24a affixed to shaft 24. Secured to the right-handextremity of shaft 30 as viewed in Fig. 3 is a conventional roll 31.Lubrication ports 22b and 27b are respectively formed within the sleeveportions 22a and 27a of the fixed and movable support means.

For the purpose of adjustably determining the minimum spacing betweenrolls 26 and 31 and of the movable support means 27 relative to thefixed support means 22, a set screw 32 is adjustably positioned withinthe pro jection 27c formed in the sleeve portion 27a of movable supportmeans 27 and the end thereof engages the projection 22c formed in thesleeve portion 22a of the fixed support means 22.

According to one form of this invention, adjustable biasing means urgesthe movable support means toward the fixed support means and therebydetermines the pressure exerted by the rolls 26 and 31 on the sliverwhich passes therebetween. This biasing means in one form comprises abiasing clip shown in Fig. 5 and designated by the numeral 33. Thedownwardly extending prongs of the biasing clip 33 are arranged toengage any of a plurality of indentations formed in the fixed andmovable support means. The indentations on the movable support means aredesignated in Figs. 3 and 4 by the numerals 34, 3S, and 36 and on thefixed support means by the numerals 37, 38, and 39 and obviously aredisposed at different distances from the pivot means 28. Thus bymanually shifting the clip 33 from the grooves 34, 37 to the gooves 35,38 or to the grooves 36, 39 a different lever arm is provided for thesubstantially constant biasing force exerted against the movable andfixed support means by the biasing clip 33. In this way, and inaccordance with this invention, the compressing force exerted by therolls 26, 31 against the sliver therebetween is adjustable. It isobvious that one, two, or three clips 33 could be used and the biasingforce could be varied in this manner.

For the purpose of enclosing the parts above described, a cover 40pivoted at 18 is provided. Mounted within an opening formed in cover 40is a trumpet 41 of conventional construction for receiving the incomingsliver into the head and means 42 is loosely mounted about the lowerextremity of trumpet 41 and is provided with surfaces configured anddisposed to engage and Wipe rolls 26 and 31 free of oil or other foreignmatter that might accumulate thereon.

As is well understood, the sliver is drawn over the guide 8, through thetrumpet 41, between the rolls 26 and 31, through the tube 16 and intocan 5. Rotation of can and of tube gear causes the sliver to form in apredetermined pattern in can 5.

While I have shown and described a particular embodiment of theinvention, it will be obvious that changes may be made without departingfrom the principlesthereof and I intend in the appended claims to coverall such changes and modifications as fall within the true spirit andscope of the invention.
